Answer:
Step-by-step explanation:
We are to determine the value of 
in scientific notation.
Given:
STEP 1: Remove the brackets.
STEP 2: Separate the numbers and index of 10.
STEP 3: Multiply the Numbers and Index of 10
STEP 4: Simplify and write in Scientific notation
Thus:
in scientific notation
No, Bec it can not be divided by itself? Anyway no also Bec it’s a decimal
Step-by-step explanation:
4(x-3) -r+2x =5(3x-7) - 9x
4x−12r+2x=15x−35−9
6x - 12 = r - 12 = r + 6x -35 -12
r=35-12
r =23
Answer:
x=-2
Step-by-step explanation:
divide both sides by 3
you get x=-2
go to -2 on the x axis and draw a line straight down, x=-2 will intercept the x axis at the point -2
same thing for y=-5 (example)
go down five on the y axis and draw a horizontal line to the y axis intercepting at point (0,-5)
Start with assigning each person with a variable to represent their height
Ebi: e
Jose: j
Derell: d
Asami: a
Ebi'd height was 2.5 cm greater than Jose's height
j + 2.5 = e
Jose's height was 3.1 cm greater than Derell's
d + 3.1 = j
Derell's height is 0.4 cm less than Asami's height
a - 0.4 = d
Ebi is 162.5 cm tall
e = 162.5
So, plug in 162.5 into any of the above equations were there is a variable of e
j + 2.5 = e
j + 2.5 = 162.5
Subtract 2.5 from both sides of the equation
j = 160 cm
Jose's height is 160 cm
Now, plug in 160 into any of the above equations where there is a j
d + 3.1 = j
d + 3.1 = 160
Subtract 3.1 from both sides of the equation
d = 156.9 cm
Derell's height 156.9 cm
so, plug in 156.9 into any of the above equations where there is a d
a - 0.4 = d
a - 0.4 = 156.9
Add 0.4 on both sides of the equation
a = 157.3 cm
Asami's height is 157.3 cm
